Yesterday morning, the former Wimbledon and US Open champion took to the social networking site Twitter to write: "Huge day for Scotland today! no campaign negativity last few days totally swayed my view on it. excited to see the outcome. lets do this!"

Murray's public support for the "Yes" campaign prompted a strong reaction, with many seeing it as a betrayal after years of support from British fans at Wimbledon, the Olympics and the Davis Cup.

But Murray insisted he was not about to turn his back on Britain ahead of their Davis Cup encounter with the United States in March.

"I will be playing for Great Britain in the Davis Cup next year, that is for sure," he said.

"I will be there in March.

"As far as I'm concerned the vote doesn't change anything in that regard."

Police have launched an investigation into a number of offensive and abusive messages from internet trolls, one of whom said they wished the 27-year-old had been "killed at Dunblane" - a massacre at Dunblane Primary School which occurred in March 1996 when Murray was a pupil.

The message, which has caused widespread revulsion, read: "Wish u had been killed at Dunblane, you miserable anti-British hypocritical little git. Your life will be a misery from now on."

Last night, Assistant Chief Constable Bernard Higgins condemned the abuse as "vile, disgusting and distasteful" and added: "We are monitoring social media and where appropriate will take action against those involved."

Murray leaves for China tomorrow where he will play tournaments in Shenzhen, Beijing and Shanghai in a bid to get back in the world's top eight and qualify for the year-end Barclays ATP World Tour finals at London's O2 Arena.
